ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 612,956, dated October25, 1898.

Application filed February 7,1898. Serial No. 669,460. (No model.)

T0 at whom it may concern:

Be it known that I, WINFIELD S. PROSKEY, a citizen of the United States,residing in the city of Jacksonville, in the county of Duval, State ofFlorida, have invented certain new and useful Improvements in Acetyleneor Oarbid Lamps, of which the following is a specification.

The invention consists of the following construction and combination ofparts, the details of which will be fully described, and the features ofnovelty then set forth in the claim.

The drawing represents a central longitudinal section of an acetylenelamp embodying my invention.

In the drawing, A represents the outer receptacle or compartment, openat the top and closed at the bottom.

B represents an inner wall concentric with wall A, having a water-tightconnection with the bottom of compartment A, also open at the top, butnot extending as high as compartment A.

I represents a pipe leading into the bottom of the compartment formed bythe concentric Walls of the compartments A and B, terminating at its topin a hopperJ and having the usual draw-oft pipe at its bottom. Thisouter annular compartment is adapted to be filled with water to near thetop of the partition B for the purpose of forming a water seal for anexpansible gas-holder.

0 represents the expansible gas-holder and carbid-receptacle. concentricwalls a I), closed at the top and open at the bottom, which are designedto telescope the concentric wall 13, the outer wall apassin g into theannular water seal between the receptacle A and the Wall B. A watertightpartition dis formed upon the lower end of the gas-holder O and isadapted to contain the carbid. I

K is a water-pipe, having a hopper L extending above the pipe F, whichpipe is provided with the usual draw-oft pipe and delivers water intothe lower liquid-chamber D, formed by the inner wall B.

When the gas-holder and carbid-receptacle is lowered into the liquidseal and into the liquid or water chamber D, the water rises around thegas-holder and carbid-chamher to a point at or about the level of thepipe F, where the Water is delivered into the other lamp.

It is formed with double.

carbid automatically in quantities sufficient at the moment for thegeneration of the necessary gas.

The gas-holder in combination with the liquid-chamber acts as a coolingdevice for the carbid-receptacle, and the gas-holder in combination withthe 1iquid-chamber,the carbid-receptacle, the water seal, and theexpansive action of the gas-holder, under pressure, act together as asafety device.

The portable character of the lamp, its safety, even if upset, in whichcase no eX- plosion could occur, only the water escaping, the extremecheapness of the lamp, and the absolute simplicity of its parts,enabling a novice. to fill and empty and clean the san1e-- all theseseem to give the invention an uncommon practical value not found in anyE is a supplementary carbid-holder. here it is designed to make thisholder E removable, the pipe F is omitted or considerably shortened andthe holder E is made of such size and shape that it will convenientlypass the pipe'F and out through the air-tight cap G in the top of thegas-holder.

M represents burners or pipes for carrying off the generated gas forilluminating or other purposes.

Having thus described the nature of my invention, what I claim as new,and desire to secure by Letters Patent, is-- In an acetylene-gasgenerator, the combination of an outercompartmenthavingdouble walls andclosed at the bottom, an inner compartment closed at both ends, andhaving an annular wall open at the bottom, said annular wall constructedto enter between the double walls of the outer compartment, a pipe inthe upper portion of the wall of the in ner compartment discharging intothe inner closed compartment, the upper portion of the inner compartmenthaving an opening into the chamber formed by the inner compartment andits double wall, and a pipe leading from the upper end of said chamber.

In testimony whereof I have hereunto set my signature.

WINFIELD S. PROSKEY.
